A Flexible Pressure Sensor Based on Porous MWCNTs/PDMS Composite Foams for Electronic Gloves

High-performance flexible pressure sensors are critical for advancements in wearable electronics, human–machine interfaces (HMIs), and health monitoring. Yet, achieving a balance between high sensitivity, broad sensing range, and seamless system-level integration remains a key challenge. Herein, we prepared a flexible pressure sensor based on porous MWCNTs/PDMS composite foams and developed a wireless smart glove system. Attributed to the unique porous architecture and the synergistic effects of conductive fillers, the sensor demonstrates superior sensing performance with a high sensitivity of 3.55 kPa–1, a broad detection range extending to 200 kPa, rapid response/recovery speeds (642 ms/295 ms), and robust long-term stability (>2,000 cycles). Building on these excellent sensing performances, the sensor has been applied to the precise recognition of Morse code and human joint motions, as well as the real-time monitoring of pressure distribution during object manipulation through integration into a smart electronic glove system. This work provides a strategy for the design and practical applications of next-generation flexible sensing systems.
